Method for shaping three-dimensional shaped object

A method for shaping a three-dimensional shaped object using a cutting tool configured to perform cutting at a first length at maximum in a predetermined cutting direction, the method comprising:

• generating cutting data, wherein the cutting data includes information on a rotation speed of the cutting tool and a feed speed of the cutting tool;
• shaping a first rising portion on a stage;
• shaping a first section having a tube shape in which an inner wall surface extends along a first direction, by laminating a shaping material in a laminating direction perpendicular to a shaping surface of the stage above the first rising portion, wherein
• a portion of a length of the first section in the first direction is shorter than the first length,
• the first direction corresponds to a direction along the shaping surface of the stage, and
• an inclination angle of a first end surface of the first section with respect to the stage, on which the shaping material is laminated, is smaller than an inclination angle of a side surface of a nozzle, from which the shaping material is discharged, with respect to the stage;
• cutting, based on the cutting data, the inner wall of the first section with the cutting tool having a cutting direction along the first direction;
• heating, for a predetermined time, the first end surface of the first section after the cutting the inner wall of the first section;
• shaping a second rising portion on the stage, wherein the second rising portion is shaped on the stage subsequent to the heating the first end surface;
• shaping a second section having a tube shape in which an inner wall surface extends along a second direction, by laminating the shaping material in the laminating direction above the second rising portion and to connect to the first end surface of the first section in the first direction, wherein
• a portion of a length of the second section in the second direction is shorter than the first length, and
• the second direction corresponds to a direction along the shaping surface of the stage;
• and
• cutting, based on the cutting data, the inner wall of the second section along the second direction with the cutting tool having a cutting direction along the second direction, wherein the predetermined time for heating the first end surface of the first section is set based on a type of the shaping material of the first section.
